Compact high efficiency intregrated direct wave mobile communications terminal


A compact mobile satellite communications system, including an integrated direct wave antenna and a low profile precision antenna positioning system, where the integrated direct wave antenna is configured to provide the minimum swept volume when steered and pointed such that it moves completely within a ten inch sphere, which provides an advantage when the system is mounted on a moving vehicle such as an aircraft, and the integrated direct wave antenna includes a refractive component as well as down conversion electronics to provide a L band signal output.

BACKGROUND OF THE INVENTION

This invention relates to a system and antenna assembly for mobile satellite communication, television, and broadband services in the Mobile Satellite Service (MSS) industry.

Conventional antenna systems incorporate reflectors to concentrate and boost signal strength or incorporate multiple antenna elements such as patch or slot arrays. In some cases multiple horns are used to provide an array of antenna elements. For purposes of this application, a horn, horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. When multiple antenna elements are used to increase aperture, the signals are summed in waveguide or printed circuit feeds and may include orthomode transducers and or combiners. The aperture is defined as the area, oriented perpendicular to the direction of an incoming radio wave, which would intercept the same amount of power from that wave as is produced by the antenna receiving it. These are subject to performance degradation due to losses in the reflections or connections used to combine and amplify the satellite signal. As a result, the size of the antenna aperture needs to increase to compensate for the accumulated losses.

In an attempt to increase aperture for mobile applications, antennas often are configured in long and narrow shapes which allow for reduced height but require wider sweep. These can be multi-element configurations or low profile dishes. These can be 34 inches wide and as high as 12 inches. When mounted on a vehicle such as an aircraft, these systems result in increased drag and lower fuel efficiency. The aerospace industry, in general, is striving for smaller and smaller antenna arrays. Smaller arrays reduce drag and reduce weight. Reduced drag and weight results is reduced fuel usage, which results in cost savings and increased profit.

There is therefore a need for an improved communications system which provides a compact high efficiency antenna for mobile applications.

SUMMARY

OF THE INVENTION

The present invention is directed to a compact high efficiency mobile satellite communication system for use in or on a vehicle is provided. This system receives and/or transmits satellite signals in the K, Ku, or Ka bands. The system comprises an integrated direct wave communications terminal, a low profile antenna positioning system, and pointing & control electronics. The system may include an integrated attitude and heading module or may utilize attitude and heading information provided by the vehicle. The control electronics determines the orientation of the integrated direct wave terminal aperture relative to the vehicle and provides the control signal to the low profile antenna positioning system so as to maintain the aperture pointed at the desired satellite.

According to another aspect of the invention, the integrated direct wave terminal receives and or transmits in the Ku band.

According to another aspect of the invention, the integrated direct wave terminal receives and or transmits in the K band.

According to a further aspect of the invention, the integrated direct wave terminal receives and or transmits in the Ka band.

According to a further aspect of the invention, the integrated direct wave terminal receives and or transmits in the Ku, K and Ka band.
